I've been working with my outgoing QOS classifications lately. Sometimes it looks like my highest priority rules are dominating. When I check the total however I see that at that point in time there is little (percentage wise) total outbound bandwidth being used. It would be great if the outgoing bandwidth pie chart would include a slice for unused bandwidth so in these scenarios the largest "used" slice wouldn't appear to consume the pie.

Yep, one mode tells you at a glance how much of your bandwidth is being used. That allows you to keep an eye on a running pie chart and notice when a rogue user hammers the router, for example.

The other (present) mode allows you to "zoom in" on the currently used bandwidth and examine it in detail. I'm quite excited by the latest GUI bits from Wes, all these seemingly small features make a huge difference when it comes to diagnosing problems. The more the merrier.
